Refactor how user-defined LWLock tranches are stored in shmem Merge the LWLockTranches and NamedLWLockTrancheRequest data structures in shared memory into one array of user-defined tranches. The NamedLWLockTrancheRequest list is now only used in postmaster, to hold the requests until shared memory is initialized.
Introduce a C struct, LWLockTranches, to hold all the different fields kept in shared memory. This gives an easier overview of what are all the things kept in shared memory. Previously, we had separate pointers for LWLockTrancheNames, LWLockCounter and the (shared memory copy of) NamedLWLockTrancheRequestArray.
